Follow advisory speed limits

7 / 30

If approaching a large amount of water on the road, what should you not do?

Reduce speed and cover the brake pedal when approaching

Test the brakes after exiting the water to help to dry them out

Apply slight constant pressure to reduce the amount of water entering between the brake drums and shoes

Maintain speed to keep momentum

8 / 30

What potential problem can happen while applying brakes on combination vehicles?

Nothing in particular

Wider turns

Skids or jackknifes

Longer stopping distances

9 / 30

When were ABS brake mandatory on all air brake trucks, buses and trailers?

Since 1992

They're not mandatory

Since 2000

Since 2010

10 / 30

If speed increases on a downgrade, what should you not do?

Repeat this process as necessary until the retarder can maintain the speed without service brakes

Use a splitter valve

Continue down the hill using the auxiliary retarder to control the speed

11 / 30

The brakes under the empty rear of the trailer receiving the same amount of application air pressure as the drive axles, without the load to hold them down onto the ground, what can happen?

May cause the rear of the trailer to slide and swing

Wheel lock-up

Longer braking distances

None of the above

12 / 30

What does water in the brake drums cause?

It cools down the rotors

Nothing

Acts as a lubricant

Reduction in braking ability

13 / 30

What does a flashing ABS dash light indicate?

Controlling the service brakes

The vehicle has just been started

A problem with the ABS system

None of the above

14 / 30

What is the cause of almost all of the brake failures and runaway crashes?

The brake system's inability to handle excessive heat

No pre-trip inspections

Malfunction of a primary air cylinder

Poor maintenance

15 / 30

When do auxiliary retarders work best?

Whenever you want them to work

At lower vehicle speeds, and with the engine just under the rated rpm

At normal speeds

At higher speeds

16 / 30

What do ABS brakes do?

Allows for shorter stopping distances

None of the above

Prevents wheel lock-up and skids

Allows for a by-pass of the air brake system

17 / 30

While braking on icy roads, what is not recommended?

Locking the wheels slightly to create friction and better traction

Using snow tires to create better traction

Icing chains to create better traction

Light braking to allow for a slow control stop

18 / 30

What is Automatic Traction Control (ATC)?

None of the above

It uses ABS sensors to monitor drive-wheel spin on slippery roads

It allows the tires to grip the road better

It slows down the vehicle to a crawl

19 / 30

Trailers equipped with ABS brakes will have an ABS warning light. Where is this light located?

At the front of the left side

At the rear of the left side

At the front of the right side

At the rear of the right side

20 / 30

What will a heavy load at the front of a trailer will cause the drive axles to have?

No difference compared to weight at the back of a trailer

Good traction for pulling and braking

Better steering ability

More momentum to get up to speed

21 / 30

What are Hydraulic Driveline Retarders similar to?

Nothing

Clutch plate

Torque converters

Transmissions

22 / 30

Antilock Brake Systems (ABS) are handled by sensors, modulators and a computer. Which statement is false? The modulators can be located...

On the wheel itself

Wing mounted directly to the relay of the axle group

Wing mounted directly to the quick release valve of the axle group

Near the chambers they control

23 / 30

At what point do air brakes generate the most ongoing heat?

None of the above

Travelling on downgrades

Braking in rainy conditions

Braking from a high rate of speed

24 / 30

What is an Electric Driveline Retarder do?

It's an electromagnet designed to retard drive shaft rotation

It's an electromagnet that can pause the driveline

It's an electromagnet that can be placed beside an axle

It's an electromagnet that can in front of the transmission

25 / 30

What does a steady ABS dash light indicate?

It's supposed to stay lit

A problem with the ABS system

The vehicle has just been started

A self-test is being performed

26 / 30

When descending on unfamiliar grades, which statement is false?

There is a balance between the retarder, speed, load and grade is reached

Select a low gear and turn on the retarder before the hill is crested

Stay in a low gear until the steepest part of the descent

On extreme grades, change gears often

27 / 30

With regard to ABS, which statement is false?

ABS brakes are different with hydraulic brakes compared to air brakes

If the tractor or trailer do not have ABS, use a light, steady braking technique

Make sure you know which units in a combination have ABS

ABS brakes work with air brakes and hydraulic brakes

28 / 30

What do exhaust retarders essentially do?

To help block the flow of exhaust

To help dissipate the exhaust

To help the back pressure move

To help the back pressure stays within the engine's back pressure capacity

29 / 30

Brake management systems are effective, when should drivers rely on them?

Never

At higher speeds

Only in poor weather

With heavy trailer loads

30 / 30

When using runaway lanes, which does not apply?

You may use these lanes for other purposes

Use the lane when the brakes no longer control the descent

A narrow steep runaway lane will be very difficult to use if the vehicle is out of control

Use the lane before the vehicle is out of control
